LM1117: Theta JA of SOT-223 Package

Part Number: LM1117

Hi Team,

Our customer would like to ask for some clarifications on the thermal data seen on the datasheet of LM1117. Previous revision (particularly rev. M) of the datasheet shows a θJA of 136°C/W while rev. N and its latest revision (rev. O) shows its θJA of 61.6°C/W. Is there any PCN or product bulletin that showed this change in its thermal info? We haven't seen this change within the datasheet rev. history.

Really appreciate your help. Thanks.


Kind Regards,

Jejomar
